Closure system for a medicament container, and medicament container having a closure system

Abstract

A closure system for a medicament container designed in the manner of a bottle mouth is intended to seal against unwanted and undesired material loss. The closure system comprises: a press-fit cap with an annular cover which has a central opening and at whose outer circumference latch elements are arranged which can be brought into engagement with an outer bead fitted peripherally on the container opening, and a closure stopper with a closure plate, on the first plate side of which there is integrally formed a thickened portion which completely fills the central opening of the annular cover and can be brought into latching engagement therewith, and on the second plate side of which there is integrally formed a radial sealing element having a cross section which is adapted to the clear width of the container opening and is slightly larger than the clear width of the container opening.

1 . A closure system for a medicament container, whose interior is accessible via a container opening designed as a bottle mouth, the closure system comprising
 a press-fit cap with a annular cover having a central opening, on an outer circumference of which ring a number of latch elements are arranged which can be brought into engagement with an outer bead fitted peripherally on the container opening, and   a closure stopper with a closure plate, on a first plate side of which there is integrally formed a thickened portion which completely fills the central opening of the annular cover and can be brought into latching engagement therewith, and on a second plate side of which there is integrally formed a radial sealing element having a cross section which is adapted to a clear width of the container opening and, with respect to the deformability of the material of the closure stopper, is chosen to be slightly larger than the clear width of the container opening.   
     
     
         2 . The closure system of  claim 1 , the closure stopper of which is made in one piece. 
     
     
         3 . The closure system of  claim 1 , wherein for the closure stopper a shaping is selected in such a way that the central region of the closure stopper forming the thickened portion is surrounded by a circumferential groove-like or trench-like recess extending into the closure plate. 
     
     
         4 . The closure system of  claim 3 , the press-fit cap of which has a reinforcing ring formed on the annular cover on its underside, surrounding the opening and inserted into the recess of the closure stopper. 
     
     
         5 . The closure system of  claim 1 , the press-fit cap of which is made of a plastic, preferably polypropylene (PP), a polyolefin, cyclo-olefin copolymer (COC), cyclo-olefin polymer (COP) or polycarbonate. 
     
     
         6 . The closure system of  claim 1 , whose closure stopper is made of rubber or of TPE. 
     
     
         7 . The closure system of  claim 1 , further comprising a locking ring which can be pushed onto the press-fit cap and can be fixed in a latching manner to the press-fit cap by means of a snap-on edge which is integrally formed on the inside and is arranged circumferentially at its end. 
     
     
         8 . The closure system of  claim 1 , wherein an RFID chip is arranged on the annular cover of the press-fit cap. 
     
     
         9 . The closure system of  claim 1 , for a medicament container, the interior of which is accessible via a container opening configured as a bottle mouth, wherein the closure system comprises:
 a press-fit cap with an annular cover having a central opening, on the outer circumference of which annular cover a number of latch elements are arranged which can be brought into engagement with an outer bead fitted peripherally on the container opening,   a closure stopper with a closure plate, on the first plate side of which a thickened portion which completely fills the central opening of the annular cover and can be brought into latching engagement therewith, and   a tamper-evident closure which is fixed on the outside of the press-fit cap and has a tear-off ring on which in its central region a sealing plate completely covering the central opening of the annular cover is integrally formed.   
     
     
         10 . The closure system of  claim 9 , wherein for the closure stopper the shaping is selected in such a way that the central region of the closure stopper forming the thickened portion is surrounded by a circumferential groove-like or trench-like recess extending into the closure plate. 
     
     
         11 . The closure system of  claim 10 , the press-fit cap of which has a reinforcing ring formed on the annular cover on its underside, surrounding the opening and inserted into the recess of the closure stopper. 
     
     
         12 . The closure system of  claim 9 , the tamper-evident closure of which comprises, for fixed connection to the press-fit cap, a connecting segment which extends between the tear-off ring and the sealing plate and is attached to the tear-off ring and/or to the sealing plate via a number of predetermined breaking points. 
     
     
         13 . A medicament container, an interior of which is accessible via a container opening designed as a bottle mouth, which is provided with a closure system of  claim 1 . 
     
     
         14 . A method comprising use of a closure system of  claim 1  for a medicament container.
